XYZ Racing Circuit Master Coilovers — Honda CIVIC EF CRX SINGLE CAM (Rear EYE) 1989-1991

The EF-chassis CRX is a 900kg lightweight that rewards mid-corner commitment and punishes anything that lets the front end wash wide on power. Circuit Master is the spec sheet for owners who have stopped pretending this car is a fast-road toy and started chasing consistent lap times at Cadwell, Anglesey or Donington National.

Built around 9720 distinct damper settings and three separate adjustment knobs, this is the XYZ Racing kit that sits alongside Racing Spec, Drift Spec and Tarmac Rally in the competitive catalogue. It is tested by XYZ race teams worldwide and engineered for circuit work rather than the school run.

What this Coilover does for your 1989-1991 Honda Civic EF CRX Single CAM (rr EYE)

The EF CRX runs torsion bars at the rear from factory and a double-wishbone front end that wants firmer control than any road spring can give it once you start carrying speed through fast direction changes. Circuit Master replaces that compliance with a properly damped, ride-height-adjustable platform that holds the front geometry steady under trail-braking into Druids-style hairpins. Compression and rebound are split across three knobs, which means you can stiffen low-speed body control without locking out the suspension over kerbs on circuit-ingress. Owners pulling the front splitter lower for downforce gains finally have a way to drop the nose without bottoming the chassis on rumble strips. The trade-off is honest: on a B-road the small-oil-passage valving will produce a faint audible note over sharp impacts, which is a circuit damper behaving like a circuit damper.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s competitive line, alongside Racing Spec, Drift Spec and Tarmac Rally. The 9720-way adjustment range is delivered through three separate knobs – high-speed compression, low-speed compression and rebound – so the damper can be tuned to a specific circuit rather than a generic compromise. The design uses small internal oil passages, which is what gives the damper its high-frequency control and circuit feel. XYZ acknowledges that over big road bumps this can produce a small audible note as oil moves through those passages; on track surfaces the issue does not arise. The kit has been tested by XYZ racing teams competing on international circuits, and the brief throughout development was sustained lap-time work rather than dual-purpose road manners.

Fitment for the Honda CIVIC EF CRX SINGLE CAM (rr EYE) (1989-1991)

This kit is specific to the EF-generation CRX with the single-cam engine and the rear "eye"-mount damper layout, chassis code HN10, model years 1989 to 1991. Confirm your rear mount style matches the eye-bracket configuration before ordering, as the EF chassis used more than one rear-damper interface across markets.
